I see Docker mentioned every other thread and was wondering how useful it is for non development things, and if so what they are.

I only use docker images supplied by the devs themselves or community maintained (e.g. Linux server.io) so they essentially tell docker what needs to be installed in the container, not me. It takes the hassle out of trying to figure out what I need to do to get the service running. If they update their app, they'll probably know best what else needs to be updated and will do that in the image. I guess you are relying on them to keep everything updated but they are way more knowledgeable than me and if there is a vulnerability, it is only in that container and not your other services.
